Buick 15881662 Rear Shock Absorber

The steering linkage and suspension components should be checked periodically, as worn or damaged parts can lead to excessive tire wear, poor ride quality, handling issues, and reduced fuel economy. To check the shock absorbers, park the vehicle on level ground, turn off the engine, and set the parking brake before checking tire pressures. Push down on one corner of the vehicle and release it, noting that it should stop moving and return to a level position within one or two bounces; if it continues to move or fails to return, the shock absorber may be worn or weak. Repeat this check at the other corners, then raise the vehicle securely on jack stands. Inspect the shock absorbers for fluid leakage, ensuring any noted fluid is from the shocks, and replace them as a set if leakage is found. Also, check that the shocks are securely mounted and undamaged, replacing them as a set if any damage or wear is observed. For the steering and suspension check, visually inspect components for damage, distortion, and leaks, particularly at the control arm mounting points, tie-rod ends, and balljoints. Clean the lower end of the steering knuckle and have an assistant move the wheel in-and-out while checking for movement at the balljoint; any movement indicates the need for replacement. Grasp each front tire to check for play in the steering system, and inspect air suspension components for damage and leaks. For 4WD models, inspect the CV boots for tears, cracks, and loose clamps, as they protect the CV joints from dirt and damage; any signs of wear or leaking lubricant necessitate replacement.

Finally, remove the shock absorber itself.
